Question

In the linear equation 2x - y = 7, if x = 2, then what is the value of y?​

Answer 1

Answer:

Answer

2x+y=7

Put, x=2

2(2)+y=7

4+y=7

y=−4+7

∴y=3.

Answer 2

Answer:

=> The value of y = 3.

Step-by-step explanation:

Given that:-

$2x - y = 7$

If x = 2,

To find:- The value of y,

For calculating the value of y,

Plug the value of x as 2, in the given expression

=> $2 ( 2 ) - y = 7$

=>$4 - y = 7$

=> y = 7 - 4

=> y = 3

Hence, the value of y is 3.
